摘 要:20 0 0年 9月 ,利用粪便示踪和野外直接观察法对准噶尔盆地东部波斑鸨 (Chlamydotisundulata)秋季栖息地进行了采样调查。结果表明 :波斑鸨秋季栖息地地势平坦 ,视野开阔 ,广泛分布旱生和盐生荒漠植物 ,植被稀疏、低矮 ,并镶嵌有相对较高的灌丛块 ;影响波斑鸨秋季栖息地选择的环境因子是植被密度、物种丰富度和物候 ;秋季栖息地内的植被密度、草本植物种数、叉毛蓬密度、结实植物密度和物种数都极显著高于对照地内的相应成分 ;生长植物密度显著高于对照地 ;而假木贼密度和琵琶柴密度显著低于对照地。Autumn habitat selection by Houbara bustards in eastern Jungar Basin,Xinjiang was studied in September 2000.It was found that the bird's preferred sites were the flat and open places,where were dominated by sparse short xero-halophytic plants with randomly interspersed bushy patches.Vegetative density,plant species richness and phenology were the most important factors that determined the autumn habitat selection of Houbara bustard.Vegetative density,herb species richness,Petrosimonia sp.density,and fruiting plant density and species richness at the autumn habitat sites were all higher than those at the control sites,and the differences were statistically significant (P<0.01);shooting plant,Anabasis sp.and Reaumuria sp.density at the habitats differed significantly from those at the controls (P<0.05),and shooting plant density relatively were high,Anabasis sp.and Reaumuria sp.density low at the habitats respectively.
